IS31FL3216A-QFLS3-TR ISSI

IS31FL3216A 16 CHANNELS LED DRIVER July 2017 GENERAL DESCRIPTION FEATURES The IS31FL3216A is a fun light LED controller with an 2.7V to 5.5V supply audio modulation mode. It can store data of 8 frames I2C interface, automatic address increment with internal RAM to play small animations function automatically. Internal RAM IS31FL3216A can sample the input signal to modulate Modulate LED brightness with 256 steps PWM the intensity of LEDs, or control 8 frames playing by PWM frequency up to 26kHz internal ADC block. Each channel can be controlled independently The LED current of each channel can be set in 256 Auto Frame Play Mode with 8 frames steps by adjusting the PWM duty cycle through an I2C 8 frames memory for animations interface. 8 channels can be used as GPIO ports. Audio Frame Mode with 8 frames IS31FL3216A is available in QFN-28 (4mm 4mm). It 8 of 16 outputs not used as LED drivers can be used as GPIO ports operates from 2.7V to 5.5V over the temperature range of -40C to +105C. 8 levels of maximum intensity control 8kV HBM ESD APPLICATIONS Over-temperature protection Mobile phones and other hand-held devices for -40C to +105C temperature range LED display QFN-28 (4mm 4mm) package LED in home appliances TYPICAL APPLICATION CIRCUIT Figure 1 Typical Application Circuit Note: The IC should be placed far away from the mobile antenna in order to prevent the EMI.
